This was built using hunch.tools. It's a free fact checker for writers or content consumers. It uses Perplexity, Llama Guard for safety check, OpenAI o3 mini and other models.
Just tried, I think it works really well. Especially I like how it breaks down a text into statements and checks each one individually. UI is also really nice. Combating misinformation sure is an important endeavor, good work!
